Detects human IL‑10 in direct ELISAs and Western blots. In direct ELISAs, approximately 20% cross-reactivity with recombinant equine IL‑10, recombinant canine IL‑10, recombinant porcine IL‑10, and recombinant feline IL‑10 is observed, and less than 10% cross-reactivity with recombinant mouse IL‑10, recombinant rat IL‑10, and recombinant cotton rat IL‑10 is observed.
Polyclonal Goat IgG
Protein A or G purified
S. frugiperda insect ovarian cell line Sf 21-derived recombinant human IL-10 Ser19-Asn178 Accession # P22301
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose.
<0.10 EU per 1 μg of the antibody by the LAL method.
Measured by its ability to neutralize IL‑10-induced proliferation in the MC/9‑2 mouse mast cell line [Thompson-Snipes, L. et al. (1991) J. Exp. Med. 173:507]. The Neutralization Dose (ND50) is typically 3-15 µg/mL in the presence of 5 ng/mL Recombinant Human IL‑10.
Please Note: Optimal dilutions should be determined by each laboratory for each application.

Detection of Human IL‑10 by Western Blot.
Western blot shows conditioned media of HEK293 human embryonic kidney cell line either mock transfected or transfected with human IL-10. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human IL‑10 Polyclonal Antibody (Catalog # AB-217-NA) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for IL‑10 at approximately 16 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Cell Proliferation Induced by IL‑10 and Neutralization by Human IL‑10 Antibody.
Recombinant Human IL‑10 (Catalog # 217-IL) stimulates proliferation in the MC/9‑2 mouse mast cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Human IL‑10 (5 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Human IL‑10 Polyclonal Antibody (Catalog # AB-217-NA). The ND50 is typically 3-15 µg/mL.
Detection of Human IL‑10 by Simple WesternTM.
Simple Western lane view shows conditioned media of HEK293 human embryonic kidney cell line either mock transfected or transfected with human IL-10, loaded at 0.2 mg/mL. A specific band was detected for IL‑10 at approximately 23 kDa (as indicated) using 10 µg/mL of Goat Anti-Human IL‑10 Polyclonal Antibody (Catalog # AB-217-NA) followed by 1:50 dilution of HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Interleukin 10, also known as cytokine synthesis inhibitory factor (CSIF), is the charter member of the IL-10 family of alpha -helical cytokines that also includes IL-19, IL‑20, IL-22, IL-24, and IL-26/AK155 (1, 2). IL-10 is secreted by many activated hematopoietic cell types as well as hepatic stellate cells, keratinocytes, and placental cytotrophoblasts (2 - 5). Mature human IL-10 shares 72%‑86% amino acid sequence identity with bovine, canine, equine, feline, mouse, ovine, porcine, and rat IL-10. Whereas human IL-10 is active on mouse cells, mouse IL-10 does not act on human cells (6, 7). IL-10 is a 178 amino acid molecule that contains two intrachain disulfide bridges and is expressed as a 36 kDa noncovalently associated homodimer (6, 8, 9). The IL‑10 dimer binds to two IL-10 R alpha /IL-10 R1 chains, resulting in recruitment of two IL-10 R beta /IL-10 R2 chains and activation of a signaling cascade involving JAK1, TYK2, and STAT3 (10). IL-10 R beta does not bind IL-10 by itself but is required for signal transduction (1). IL-10 R beta also associates with IL‑20 R alpha, IL-22 R alpha, or IL-28 R alpha to form the receptor complexes for IL-22, IL-26, IL-28, and IL-29 (11‑13). IL-10 is a critical molecule in the control of viral infections and allergic and autoimmune inflammation (14‑16). It promotes phagocytic uptake and Th2 responses but suppresses antigen presentation and Th1 proinflammatory responses (2).
